The fungal family represents ubiquitous and ecologically significant components of soil ecosystems across terrestrial habitats. Through an integrative taxonomic approach combining multi-locus phylogenetic analyses (ITS, LSU, SSU rDNA, , and ) with detailed morphological examinations of rhizosphere soil isolates, four novel species within this family were proposed. This study elucidates the morphological distinctions of novel species from allied species and the phylogenetic relationships among the novel and existing species within the family. sp. nov. (closely related to ) is distinguished by its globose sporangia and sporangiospores. sp. nov. (clustering with ) is characterized by spiky collarettes. sp. nov. (a sister to ) exhibits distinctive ampulliform swellings. sp. nov. (clustering with ) is named for its geographic origin in Tibet. As the eighth installment in a systematic investigation of early diverging fungal groups in China, this work expands the global taxonomic inventory of to 148 species, underscoring the ongoing discovery of cryptic biodiversity within this ecologically pivotal group.
该真菌家族是陆地生境土壤生态系统中普遍存在且具有重要生态意义的组成部分。通过将多位点系统发育分析（ITS、LSU、SSU rDNA等）与根际土壤分离物的详细形态学检查相结合的综合分类学方法，提出了该家族中的四个新物种。本研究阐明了新物种与近缘物种的形态差异以及该家族中新物种与现有物种之间的系统发育关系。新种（与密切相关）的特征是其球形孢子囊和孢子囊孢子。新种（与聚类）的特征是有刺的领状结构。新种（是的姐妹种）表现出独特的壶形肿胀。新种（与聚类）因其起源于西藏的地理区域而得名。作为对中国早期分化真菌类群系统研究的第八部分，这项工作将全球的分类名录扩展到148种，突出了在这个生态关键类群中不断发现的隐秘生物多样性。
